I've been using Ubuntu 11.10 (fresh install) for a month on a Asus N43SL.
Mouse pointer has gone haywire this morning. It had been working fine before except for the occasional freeze which was usually fixed by the following:
rmmod psmouse modprobe psmouse
But, this hasn't been working this time. Totally lost trackpad function an hour ago. Connected USB mouse but the cursor is still jumpy.
I installed Synaptiks Touchpad manager and the problem went away for about 30 minutes (no reboot).
I am currently using the "disable touchpad automatically when usb mouse is plugged in" option in Synaptiks. The mouse cursor is not jumpy as when mouse is plugged in but as soon as mouse is unplugged and touchpad is active; mouse cursor goes haywire.
So, the question is how to prevent the mouse pointer from going haywire?
